[PATCH] update libm-test-ulps for new exp

[Szabolcs Nagy]

Update error bounds for the new exp implementation on alpha, hppa,
m68k/coldfire, microblaze, mips/mips32, mips/mips64, nios2, powerpc,
riscv/nofpu, riscv/rv64, s390, sh and sparc.  Only non-nearest
rounding ulp bounds increased.  Did not run the math tests on real
hardware, but used the following ULP bounds to generate the new files:
